Impact windows and hurricane shutters both satisfy Florida’s opening protection requirement, and both can earn an insurance credit. The difference is in how you live with them. Shutters cost less up front and protect only when they are closed. Impact windows cost more and protect every day without any work. Here is a side-by-side comparison for South Florida homeowners.
Side by side
| Impact windows and doors | Hurricane shutters | |
|---|---|---|
| Up-front cost | Higher: a full home typically runs $12,000 to $30,000 | Lower, depending on type (panels, accordion, roll-down) |
| Protection | Always on, 24 hours a day | Only when deployed before a storm |
| Labor before a storm | None | Hours to install panels or close accordions, every storm |
| Security | Laminated glass resists forced entry | None unless closed |
| Energy and UV | Low-E glass blocks heat and UV year round | None |
| Noise reduction | Yes, laminated glass | No |
| Natural light during a storm | Yes | No, the house is dark |
| Appearance | Clean, no tracks or boxes | Visible tracks, hinges or housings |
| Insurance opening protection credit | Yes | Yes, if rated and covering every opening |
| Home value | Adds value and is a selling point | Neutral to slightly positive |
| Maintenance | Minimal | Lubrication, storage, replacing lost panels |
When shutters still make sense
- You plan to sell soon and want the lowest-cost way to meet code.
- You have a few odd openings that are hard to fit with impact glass.
- You are protecting a rental or a second home where energy savings matter less.
When impact windows are the better choice
- You live in the home year round and want protection without the pre-storm scramble.
- You want lower cooling bills, less noise and better security every day.
- Your existing windows are old, leaky or foggy and need replacing anyway. Replacing them with impact glass solves both problems with one project.
- You want a cleaner look and higher resale value.
Can you combine them?
Yes. Some homeowners install impact windows on the main openings and keep rated shutters on a garage side door or a utility window. For the insurance credit, every opening must be protected one way or the other. Once a home has impact windows and doors everywhere, the shutters can come down for good.
The cost gap is smaller than it looks
Impact windows replace your existing windows, so part of the cost is a window replacement you may need anyway. Add the insurance credit, lower cooling bills, and current offers of 20% off plus $0 down financing, subject to credit approval, and the payback period shortens considerably. See our cost guide.
Frequently asked questions
Are impact windows better than hurricane shutters?
For most owner-occupied homes, yes. Impact windows protect without any work before a storm and add security, energy savings, noise reduction and resale value. Shutters cost less up front but only protect when deployed.
Do I need shutters if I have impact windows?
No. Impact windows and doors rated for large-missile impact provide opening protection on their own. Once every opening is impact-rated, shutters are not required.
Do impact windows get the same insurance discount as shutters?
Both qualify for the opening protection credit when every opening is protected with rated products. Check with your insurer for the exact amount.
Can I keep my shutters and add impact windows?
Yes, but once every opening has impact glass, the shutters serve no purpose and most homeowners remove them.
Which is cheaper over 10 years?
Impact windows usually close the gap through insurance credits, energy savings and avoided shutter maintenance, while also replacing aging windows. The exact math depends on your home and policy.
